Union for a Popular Movement (Union pour un Mouvement Populaire [wiki] or UMP) is a French conservative political party. During the summer, besides handing out leaflets, activists for the party also wore this clever flip-flop that imprinted the party's initials on the sand.

Funny where these ideas originate...temple prostitutes in Corinth in Greece wore sandles that spelled out "follow me" in Greek in the sand. I wonder if they realize that's where they're coming from? :)
